Bohodrfld referred to in time Letter- Patent me making put of the some.

1, HENRY DIOKIbl'SON, of Marlborough, in the county of Hartford and State of Connecticut, have inventedcertain Improvements'in Washing-Machines, of which the following is a specification.

llfatm'e and Objecta'of the Invention.

My invention consists in a box into which the clothes to be cleaned are put, and secured from leakage on all sides. v

This box is hung on centers, on which it is made to revolve.

Inside the box with the clothes are small oblong blocks of wood, or othe'fisnitable material, rounded on the ends, which tumble back and forth with the clothes and assist the cleansing process.

' Descriptionof the Accompanying Drawing. The figure shown is a side elevation, with a part of the box broken away and shown in section, for the purpose of showing the interior 'of the box and its outwardconstruction.

General Description.

The letter it indicates the frame of the machine, or rather one-half of it, a duplicate of the part shown being upon he oppositeside'of the box, both of which duplicates are properly joined together.

7 The letter b indicatesthe box, which, in this case is square in itscross section, and rectangular in its longitudinal section.

It is hung on hearings or centers, one of which, 0,

This pin is attached to the frame by the chain h, I and hangs thereby, when not in use, for locking the box in its level position.

0n the top of the box is a round hole, for the introduction'and withdrawal of the clothes.

This orifice has a cover or stopper, 'i,'just fitting into it, with convex ,edges', and with a ring of rubber, j, to make the joining safe from leakage.

From each side of the box rise metal bars 7:, which hook over at a right angle toward each other at their upper extremities.

Under these hooked ends fit the 'ends of. the bar I, which bar has a thumb-screw, m,- in its center, whose lower end bears down upon the top of the cover 1', by the turning of which screw-the cover can be forced down into its seat with any desired pressure.

This bar being readily rem ovable, when the thumbscrew is loosened, from under the hooked ends of the bars It, does not interfere with the removal or putting in place of the cover. 7 I

The letter a indicates a knob attached to the top of the cover, by which it can be conveniently handled.

- Within the box are one or more tumbling blocks, 0, which are oblong cylinders, with rounded ends or eggshaped. r

I do not claim the exclusive right to use a block of all shapes, but air-oblong block will tumble more than.

almost any other while the-box is rotated, and the shape of these blocks is an; essential feature of my invention.

- The letter 1) indicates a plug for letting oh the waste;

water. I

' Claim.

I claim as my invention- I Theoblong boxb with the blocks 0, cap I, and thumbscrew m, with its gearing, shafts, and crank, to give motion, iii combination with the frame a, chainand staples h and g, the whole constructed and arranged substantially as and for the purposes -set forth.
